Which is an action of flexor digitorum longus?

Explanation:
Flexor digitorum longus mainly flexes the distal joints of the four smaller toes. Its tendon runs to the distal phalanges of the second through fifth toes, allowing for flexion at those final joints. This action is distinct from the great toe, which is flexed by flexor hallucis longus, and from toe extension or ankle dorsiflexion, which are handled by other muscles. So, flexing the 2nd through 5th toes is the best representation of what this muscle does.
